BEZEL FOR CLOCK-CRYSTALS.

To all whom it may concern:

Be it known that I, WALTER J. HER- SGI-IEDE, a citizen of the United States of America, and resident of Cincinnati, county of Hamilton, and State of Ohio, have invented certain new and useful Improvements in Bezels for Clock-Crystals, of which the following is a specification.

An object of my invention is to produce a new and improved bezel for clock glasses or crystals, in which the glass or crystal may be easily mounted.

The ordinary form of bezel usually employed consists of a ring provided with an annular groove, into which he crystal is sprung. Such a construction necessitates extremely accurate work in grinding the crystal or glass, and in addition to the fact that the crystals are liable to be broken dur ing the operation of inserting them in the bezel, they are under a strain when in the bezel, and consequently are liable to be shat tered by a slight jar or blow.

A further object of my invention is to produce a bezel which overcomes the difficulties encountered with the ordinary form of bezel, and which presents the same appearance as the ordinary bezel.

In the drawings accompanying and forming a part of this application, Figure l is a front elevation of a bezel embodying my invention, together with a crystal mounted in the bezel. Figs. 2 and 3 are respectively a plan view and a side elevation of the device shown in Fig. 1. Figs. 4 and 5 are respectively sectional views on the lines 4 & and 55 of Fig. 1.

The bezel illustrated is an embodiment of my invention comprises two rings 6 and 7, which are adapted to be secured together by means of screws 8, for the purpose of securing the glass or crystal of the clock in place. The ring 6 is hinged to a dial ring 9, encircling the face of the clock and mounted on the clock casing, and is provided on its outer face with a forwardly projecting annular flange or shoulder 10, which is located around the outer edge of the ring, and which encircles the clock crystal 12, when it is in place on the ring 6. The ring 7 is provided at its outer edge with an inwardly projecting annular flange or shoulder 11, which is adapted to encircle the flange 10, when the Specification of Letters Patent.

ring 7 is in place on the ring 6. The screws 8 are preferably mounted in countersunk holes, which extend transversely through the ring 6, the heads of the screws being located on the inner side of the ring. The screws engage tapped holes provided in the inner face of the ring 7 and extending only partially through the rin In assembling the bezel, the glass or crystal 12- is located on the ring 6, so that its edge is encircled by the shoulder 10. The ring 7 is then placed on the ring 6, so that its flange 11 encircles the shoulder 10, and so that its inner edge contacts with the outer face of the crystal and provides a slot or groove for the edge of the crystal. After the crystal and the ring 7 are in place on the ring 6, the separate parts of the bezel are secured together by means of the screws 8. By tightening the screws, the crystal may be secured in place, so that it will not rattle or vibrate while the clock is striking. The crystal is not, however, subjected to inherent strains which are liable to cause it to break at the slightest jar or blow, since its edge fits easily into the groove form-ed by the cooperation of the rings 6 and 7, and since it is merely clamped in place between the two rings.

One of the advantages of my invention is that it does not require an expert to replace the glass or crystal, and the crystal does not have to be a curately ground. In addition to this, the bezel presents the appearance of the ordinary one piece bezel and does not project too far beyond the forward face of the frame of the case of the clock.

What I claim is In combination with the dial ring of a clock, a bezel for the clock crystal comprising an inner ring hinged to the dial ring and provided with a forwardly projecting annular flange encircling the edge of the crystal, an outer ring provided with an inwardly projecting annular flange encircling said forwardly projecting flange, and screws extending through apertures formed in the inner ring and engaging apertures in the outer ring for securing the rings together.
